NCS2632 Evaluation Board
User's Manual
Introduction
This document gives a description of the NCS2632
evaluation board with the bill of materials (BOM), board
schematic, and evaluation setup. The NCS2632 evaluation
board has been designed to help for a quick evaluation of the
NCS2632 audio line driver performance.
This document is to be used with the NCS2632 data sheet.
The data sheet contains full technical details regarding the
NCS2632 specifications and operation.
The board is implemented in 2 metal layers. The layers
have thicknesses of 35 mm (1 oz). The PCB thickness is
1.6 mm (63 mils) with dimensions of 115 ×100 mm
(4.5″×3.9, respectively).

QUICK START PROCEDURE WITH DIFFERENTIAL SETUP
By default, each channel is set up in a differential
configuration with a gain of 2 V/V. Follow this procedure to
quickly get familiar with the evaluation board features.
1. Make sure that the VDD jumper and UVP
detection supply jumper are in place. Remove all
input jumpers to ground. Table 1 summarizes the
position of each switch and jumper.
2. Connect a 3.3 V supply between the VDD pin and
GND.
3. Set the EN switch to high to enable the IC. Check
the supply current. Verify that EN is high with a
multimeter, if necessary.
4. Use the voltmeter to measure the VSS pin. It
should measure near –VDD.
5. Apply a sine wave (f = 1 kHz, 1 Vpp) across INLP
and INLM. Observe the waveform at OUTL.
6. Apply a sine wave (f = 1 kHz, 1 Vpp) across INRP
and INRM. Observe the waveform at OUTR.
For more information and circuit examples refer to the
Application Information section in the data sheet.
